Abstract

PURPOSE: To obtain a tablet having a clear carved seal, by applying a substance having color tone different from that of the protrusion part of the carved seal of the tablet having a carved seal to the dent part of the carved seal, and, if necessary, covering the dent part of the carved seal with a film-forming solution.

CONSTITUTION: A tablet having a carved seal, preferably the slightly covered tablet, is covered with a substance having color tone different from that of the protrusion part of the carved seal by using a coating pan, etc. Naturally a substance which has been used for forming a film can be used as the substance, and an additive ordinarily useful for tablet can be used without limiting it specifically. It is usually blended with a dyestuff, etc. having a color tone different from that of the protrusion part of the carved seal. An excess amount of the substance can be removed by screening by a sieve, grinding by a brush, etc. After that, if necessary, the tablet is covered with a film-forming solution such as water-soluble, enteric solution, or solution soluble in the stomach, to give a tablet having a clear carved seal.
